Digital display tube provides clear, accurate readouts. Regulation is controlled by a precision encoder rather than a potentiometer, delivering higher accuracy, greater stability, and longer life. Power variants and capabilities: the 41A thyristor version can control loads up to 1000W, while the 100A thyristor version can control loads up to 3000W. Robust board design for easy installation: doublesided welding and an integrated component layout create a compact, machinefriendly board that is easier to mount inside a machine casing. Flexible control features: adjustable single and double pulse modes, spot welding counting, synchronous triggering, and poweroff saving to preserve settings and important data. Practical and compatible design: tailored for spot welding applications requiring reliable control and precise timing, suitable for integration into equipment built for spot welding tasks. Use scenarios Electronics assembly: precise tab welding for copper or aluminum conductors and connectors on PCB assemblies, where stable regulation and repeatable pulses improve joint quality. Battery pack manufacturing: spot welds for cell tabs and interconnects in Liion or Nibased packs, leveraging accurate pulse control and counting for consistent welds. Small to midscale metal fabrication and : controlled spot welds on thin sheet metal or connectors, with adjustable pulse options and synchronous triggering to prevent overheating. Key attributes at a glance: digital display with encoder regulation for accuracy and longevity; two power options (41A up to 1000W, 100A up to 3000W); doublesided welded board with optimized component layout for easier machine mounting; single/double pulse selection with spot weld counting, synchronous triggering, and poweroff saving for reliable, repeatable performance.
